Feel if you play with a killer instinct and ruthlessness, you play much better as opposed to just playing light leisurely tennis. I have found the formula to win is to play every ball like it's match point. Level is strong 4.5. Play open, 35s. When I lose 60 60 you don't knock your connquerer in any way, you salute him. For a chump to call his double bagel master a pusher is not acceptable. It's all part of the mental and physical battle, never let the opponent have an inch on the court or off ) At least that's how I do it. Give respect and tolerate no disrespect.
